Product Description

The DURAVENT 810003146 is a FasNSeal AL29-4C stainless steel vent pipe section rated for venting systems that require durable, high-temperature performance. Constructed from AL29-4C alloy stainless steel, this pipe section measures 4 inches in diameter and 3 feet in length, weighing 9.80 pounds. It is rated for a maximum operating temperature of 480 degrees F and carries UL1738 listing, meeting the standard for venting systems serving gas-fired appliances. Licensed HVAC technicians and mechanical contractors install this pipe as part of Category III and Category IV positive-pressure vent systems.

This vent pipe section is used in residential and light commercial applications where a UL1738-listed AL29-4C stainless steel vent system is required. Typical installations include high-efficiency condensing furnaces, boilers, and water heaters that produce flue gases requiring corrosion-resistant positive-pressure venting. The FasNSeal system is designed for tool-free assembly, making it a practical choice for new installations and retrofits in tight mechanical spaces.
